155Mbps BIDI,(SMF
20km 1310/1550),
Simplex LC

H/W Version: 1

The LevelOne SFP-7321 is a high performance, cost­eective SFP transceiver. It provides up to 155Mbps
bi-directional data transfer rate at distances up to
20km on a single ber core. These bi-directional SFP
Transceivers allow data transfer in either direction
through a single optical ber by employing separate
wavelengths travelling in either direction.

LC Simplex Connector

SFP-7321

The SFP-7321 transmits using a wavelength of
1310nm and receives using a wavelength of 1550nm.
When coupled with the LevelOne SFP-7331 transceiver
which transmits at and receives at the opposite rates
(1550nm RX and 1310nm RX) you get bi-direction
data communication on a single ber core.
